Application filed May 20, 1920. Serial No. 382,901.

To aZZ whom it may concern:

Be it known that I, LEO J. Dory, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Film Reels, of which the following is a specification.

My invention relates to improvements in safety film reels.

The object of my invention is to provide a film reel which will be fire proof in so far as concerns its ends, which is simple in construction, cheap to make, durable and strong, not liable to get out of order, and to which a film may be readily attached or detached.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates the preferred embodiment of my invention,

Fig. 1 is an end elevation, partly broken away of my improved film reel.

Fig. 2 is an enlarged vertical sectional view on the line 22 of Fig. 1.

Fig. 3 is a cross section on the line 33 of Fig. 2.

Fig. 4 is a perspective view of the hub.

Fig. 5 is a perspective view of one of the collars. 1

Fig. 6 is a stretch out view of the hub prior to its being formed into a cylinder.

Similar reference characters designate similar parts in the different views.

1 designates two solid or plane heads, preferably of sheet metal, such'as sheet steel, each having an axial opening 2. 3 designates a tubular axle having its ends bearing respectivelyagainst the inner sides of the heads 1, the axial hole of the axle being-preferably, of the size and shape of the openin s 2.

1 designates a hub comprising pre erably a sheet metal strip formed into cylindrical shape, the strip at one end having a notch 5, which, when the ends of the strip abut against each other, forms a longitudinal slot in the hub, which is adapted to receive a film securing device, not shown. The ends of the hub 1 bear respectively against the heads 1. Each end of the hub 1 is provided with one or more notches 6. p

7 designates two collars mounted on the axle 3 and fitted Within the hub 4."- Each collar 7 is provided with one or more peripheral projections 8 respectively fitted in the adjacent notches 6 of the hub 4.

A plurality of transverse pins or rivets 9 are respectively riveted at their ends to the heads 1 and extend through and have shoulders 10 which bear against the collars 7. thereby holding the collars and the hub 1 tightly against the heads 1, and serving to With a suitable covering for the film on the perlphery of the reel, the latter will fully protect the film carried thereby from fire.

I do not limit my invention to the structure shown and described, as many modifica tions, within the scope of the appended claims, maybe made without departing from the spirit of my invention.

What I claim is 1. In a safety film reel, a drum comprising two plane heads each having an axial. opening, a tubular axle having its ends abutting respectively against said heads, the hole in the axle registering with and corresponding in size and shapeto theopenings in said heads, a hub encircling the axle and having its ends respectively abutting against said heads, one end of the hub having a notch, the hub having a longitudinal slot forthe insertion of a film, a collar fitted on the axle and provided with a peripheral projection fitted in the notch of the adjacent end, and securing means connecting the heads and holding the heads against the hub and axle, substantially as set forth-.,

2. In a safety film reel, a drum comprising two plane'headseach having an axial open-.

ing, a tubular axle'having its ends bearing. respectively agalnst said heads, a hub encircling the axle and jhavlng at one end a adapted to receive a film securing device, two j collars fitted in sald hub and encircling'and ing two plane heads each having an axial notch and "provided witha longitudinal slot '1 notches respectively, two collars fitted on said'axle' and in said hub, each collar having a peripheral projection fitted in the notch of 10 the adjacent end of the hub, and securing means connecting the heads and extending through said collars, substantially as set forth. Y

M In testimony whereof I have signed my 15 name to this specification.

LEO J. DOTY.
